I went to best buy today and picked up a radar detector and the sales rep told me that since the M3 has polarized glass i shouldn't use suction cups to hold the detector on the front window. Why is this? Is it true or does it even matter????
Sounds like crap to me. Yeah, you want to be careful with your polarized glass, but suction cups shouldn't hurt anything. If you are that worried about it, velcro it to your dash instead. Or get a sunvisor clip...
Good luck,
Paco
